Adding a Turntable to a Wireless Speaker: Follow the Signal Path
The connector is only one part of the compatibility question.
Identify the turntable output
A turntable’s output may need a phono preamp before it can feed an ordinary line-level input. Check the turntable documentation for a built-in preamp and the setting required for the intended connection. If it lacks one, plan an appropriate external unit. Do not assume that matching plugs prove the signal is ready for the speaker.
Check the speaker input
Some wireless speakers accept an analog source directly; others require a specific adapter. Sonos documents a separate line-in adapter for the Era 100. A USB-C socket alone is not proof that an inexpensive generic adapter or every USB audio source will be supported.
Consider the system role
If the speaker also belongs to a home-theater or multi-room arrangement, check the input rules for that exact configuration. A product can support a feature in one role while limiting it in another. Map the complete route from turntable to every speaker you want to hear before ordering equipment.
Budget for the complete connection
Add the required adapter, cables and any phono preamp to the purchase comparison. An existing amplifier and speakers may already provide a straightforward path; a network streamer can add different options to that system. Choose the fewest components that accomplish the intended use reliably according to the manufacturers’ documentation, and keep the setup understandable for everyone who will use it.
